I was at lunch today at Fry's and wanted to see the x34 Predator. They didn't have it, but a colleague of mine brought up why not do a TV for a fraction of the cost. So My question is what is the true drawback now with a 4K LED TV for gaming and computer work? Some of these TV's refresh at 120hz. The lag? Is it any different from console gaming? What's the true drawbacks for someone looking at TV's instead of a "Monitor" for school, work, and gaming?
